Compared with DOP, DINP has a larger molecular weight and a longer carbon chain, so it has better aging performance, migration resistance, extraction resistance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP is slightly worse than that of DOP. DINP is generally considered to be more environmentally friendly than DOP. DINP has advantages in improving extrusion efficiency. Under typical extrusion processing conditions, DINP reduces the melt viscosity of the compound more than DOP, which can help reduce die pressure, reduce mechanical wear or increase extrusion productivity (up to 21%). This productivity increase can be It can be realized without changing the product formula and production process, without additional fixed investment, without additional energy consumption, and maintaining product quality.

This product has good compatibility with PVC, and will not precipitate even if it is used in large quantities; its volatility, migration, and non-toxicity are better than DOP (dioctyl phthalate), which can endow the product with good light resistance and heat resistance. , aging resistance and electrical insulation properties, the overall performance is better than DOP. Because the products produced by this product have good water resistance and extraction resistance, low toxicity, aging resistance and excellent electrical insulation properties, they are widely used in toy films, wires and cables.
